Application filed January 20!, 1908. Serial No. MLEBdi To all whom it may concern:

Be it known that l. Annular E. GUMZ, a citizen of the Unit l lates, residing at Milwaukee, county of lililwaukee, and State of Wisconsin, have invented. new and useful Improvements in if following is a specification.

My invention relates to improvements in that class of carbureters which is adapted to be used in connection with the cylinder of a gas engine.

The construction of my device is explained by reference to the accompanying drawings,

in which- Figure 1 represents a vertical section thereof, and Fig. 2 a rear view, part in section.

Like parts are identified by the same reference characters in both views.

1 represents the valve chamber of my upparatus.

2 is the inlet air duct, 3 the exhaust duct which is adapted to be connected withilie cylinder of an engine.

5 is an inlet duct which is adapted to be connected with the gasolene tank; or other liquid fuel supply gasolene is adapted to be admitted to the carburetor with each strolre of the engine, with which the exhaust duct 3 is connected. The inlet air duct 2 is provided with a valve 6 which is pivotnlly supported from the valve chamber 1 the carburetor upon the pin 7'and is adapted to be normally retained in the closed position shown, by the spring actuated arm 8. The arm 8 is pivotally supported from the chamber 1 upon the bolt 9 and bears at its opposite end upon the angular lug 10. The angular lug 10 is formed integrally with the valve 6.

11 is an actuating spring from which motion is communicated through the arm 8 to the valve 6 through the shoulder 10 as stated. The spring 11 is connected at one end with the arm supporting bolt 9 and at its opposite'end with the walls of the chamber, and it is sowound that it is adapted by its recoil to turn the bolt 9 thereby throwing the free end of the arm 8, which is rigidly connected with said bolt 9 downward against said log 10, whereby said valve 6 is normally retained in the closed position shown. lit will be understood that with each forward stroke of the pistonof be caused to rush in wil b mnvetl to the open position indicated Jarburetcrs, of which the and through which the from left to right Specification of Letters out.

lfaten'ted Sept; 1 12; 19th by dotted lines. l llhen, however, the piston has reached the limit of its forward move.-

ment, the valve 6 will be'closed by the recoil -of said spring ll.-

12' represents a valve by which the admission of gasolene or other liquid is controlled. The valve 12 has its seat upon the inner end of the duct 5 and is rovided with a protruding stem 13.. Tile stem 13 extends through an aperture in the arm 8 and is provided with a nut 1a which is adapted to contact with-the upper side of said arm 8 as said arm is raised, and a nut 15 which is adapted to contact'with the lower side of said arm 8 as the latter is lowered, thereby forcing said valve 12 to its seat. It will now be understood that as the valve 6 is with each forward stroke of the engine,

motion will be communicated therefrom I through the lug 10 and arm 8 to said valve l2, wlu-zroby said valve will be opened andpermit a small. quantity of gasolene or other liquid fuel to simultaneously enter the car bureter. l v'hen, however, said valve 6 is closed said valve l2 will also be moved in the opposite direction and closed.

16 is a guide bearing for the upper end of the valve rod 13 whereby said valve 12 is guided to and from its seat.

17 is a screen which serves to retard the escape of the unvaporized'fuel. bearing 16 and screen 17 are supported upon the radial arms 18, and said radial arms 18 The guide I are in turn supported from the walls of the outlet duct 3 substantially as shown.

19 is a damper which is pivotally supported in the outlet duct 3 upon a shaft 20, and said shaft 20 issupported at its rcspective ends in thewalls of said outlet duct. 21 isan'arm by which saiddamper 19 is opened and closed and the escape of gas thereby regulated and controlled.

22 is a handle by which the valve 12 may be raised by the manual act of a person, whereby a small quantity I other liquid fuel may be admitted into the carbureter, preparatory to startingthe engine. 1 Motion is communicated from the handle 22 to the valve 12 through the shaft 9 and arm 8. It will be understood that after the liquid fuel has been thus admitted and the engine started in the ordinary way, the

fluid controlling valve will be automatically moved, whereby the liquid fuel will there of gasolene or after be automatically supplied as hereiir before described.

' a adapted to be turned by the current of escap- .valve 12 isrotated and such forei While I have described my apparatus as being adapted to be used with gasolene or other liquid fuel, it is obvious that the same may, ifidesired, be operated in substantially the same manner with ordinary illuminating or fuel gas, when. the required quantity -of air to produce combustion will be admitted as stated through said inlet duct 2.

To prevent the liabilityof sediment ac-' cumulating upon the. seat of the fuel controlling valve 12, I preferably provide the ugper end of the valve stem with a rigidly xed fan or bladed wheel 25, which is inggas through the outlet duct whereby said I stances as might otherwise accumu ate on the seat of the valve will be removed.

. It will be understood that-the quantity of fuel admitted with each stroke of the engine iwilljdepend upon the height that the valve '121is raised from its seat. It therefore follows that whenthe damper 19 is partially closed itwill throttle the escaping gas, and I airvalve 6,'whereby the stroke of the lever consequently limit the movement of the inlet 8 and the fluid controlling valve 13 will also be proportionately l quantity of fuel admitted with each stroke of the engine will correspond with the quantity of air admitted.

. Having'thus described my invention what I claim as'new and desire to secure by Letters Patent is,'-

said arm being adapted to normally retain. both the said air valve and liquid control ling valve-mtheir closed positions, while motion is communicated from said inlet air valve as the same is opened through said;

spring actuated arm to saiddiquid control;
